To all whom z't may concern.:

Be it known that 1HENRY J. MAs'rnN- BROOK, a citizen of the United States, residing at Lakewood, county of Cuyahoga, and.-

State of Ohio, have invented la certain new and useful Improvement in Automobile Door Hinges, and declare the following to bea full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a partyof l this specification.

This invention relates to an improved automobile doorvhinge. I

It is essential in hinges of this class that the joints and cracks between the in-terengaging vparts of the opposed `plates be concealed so far as possible for the reason that, no twithstandingr how t-horoughlyand effectually the hinges are painted, enameled, oi

otherwise coated, the coating about these working parts becomes cracked or worn away exposing the metal to water and moisture and resulting in its rusting, the rustaccumulating about the joints or cracks and running. down the side of the hinge and presenting an unsightly appearance. The concealment of the joints and cracksV has been comparatively easy in cast metal hinges forA the hinges. could be moulded in a shape accomplishing this end, but cast hinges are expensive, unduly heavy, land more or less easily broken. A,

It is the pur ose of ,thisI invention to provide an automo ile door hingepossessingthe foregoing essential feature and` to construct "the same-of sheet metal thereby rendering it'` cheap, convenient of manufacture, light and stro and to design it so that the pintle may e readily removed to expedite detachment of the door.

Iam aware thatautumobile door hinges have been made of sheet inetal, but none has beenproduced of the ty e to which this invention relates wherein t e cracks and joints betweenwthel hingejplates have been concealed. y A hinge possessing the advantagesy above set forth and constructed in accordance with my invention'is illustratedy in the drawingyaccom anying and forminga part hereof Figure 1 isa perespective` view O fthe -applied to an automobile, adjacent parts of refer to the opposed hinge plates as the inner plate 1 and the outer plate 2, the former ybeingdesigned for attachment to the pillar of the body A, and the latter to the adjacent frame member of the door B. When the door is closed, the bodyA portions of nthe plates'l and 2 lie iatagainst each other, as shown in Figs. 4 and 5, and their outer ends are turnedlaterally in a direction away from the door in' accordance with the usual construction of hinges of thisv type. The outer end ofVA the inner plate terminates in tongues, two being `shown in the present instance that' are shaped to form pintle encircling knuckles 5, as best illustrated in Fig. 5.

The corresponding end of the outer plate 2 is wrapped about the knuckles 5 for a considerableepart of 'their circumference, terminating therebeyond-in three tongues 'that are shaped to form knuckles 6, one being disposed betweenthe knuckles 5 of the former plate and the twoothers above and below the ormer knuckles, as lshown in Figs. 2, 3 an 6.; Y

To improve thev appearance of the hinge,

I' may provide topand bottom platesl '8., and 9, respectively, which are preferably integral parts of thev outer plate 2` and which concealV the outer end ofthe inner plate-when the parts are inclosed condition. The plates 8 and 9 have 4apertures in axial alignment with the knuckles 5 and 6 and a through these apertures an the knuckles to connect the plates in the usual manner. The withdrawal of the pintlemay be initiated by int-le 10 extendsv driving a. suitable instrument up through the aperture ofthe bottom plate 9 when it is desired to remove the door.

From this description it will be seen that royinvention provides af'hinge of `simple construction, one that is cheap, attractive of appearance, and #wherein the joints and cracks between the interengaging `parts of the yopposed plates are effectually concealed from view When the hinge is applied to an automobile and viewed from usual angles.

The distance to Which the unbroken surface,`

of `the outer plate extends about the joint between the plates is indicated in Fig. 5.

What I claim is.: lf'A hinge of the class described comprising opposed plates, oneterminating at one end in a series of knuckles, and the other having its end portion extended about and partially concealing said'knuckles and terminating inknuckles interengaging those of the former plate, the latter plate having parts turned at right angles to its body ortion over the end knuckles, said parts aving apertures in axial alignment with 'the knuckles, and a pintle extending through the hinge is in closed condition, said' plates hav-v ing aprerturesin axial alignment with the knuckles of the plates,` and a pintle extending through said apertures and knuckles.V

3.' A n automobile doorlhinge comprising a" pairof sheet metal plates, one terminating at one end in a series of knuckles, the correspondin end of the other plate extending about an concealing the knuckles of the first plate and itself terminating in a series i of knuckles disposed between those of the first plate and being in endwise engagement ltherewith and having an internal diameter substantially equal to the internal diameter of the knuckles of the first plate, and a pintle extending 1 through the knuckles of the two plates.

4. In a hinge, a body member having vits 'outerend portion provided with a longitudinal channel and a hood closing the outer end of said channel, and a complementary member having a hinge pin connection With the `outer end of said body member. and adapted at its louter end. portion to lit Within said- -channelsaid hood partially inclosing and concealing the hinged end of said complementary membert 5. In a hinge, a body member having its outer end portion provided with a longitudinal channel and a hood closing the outer end of said channel, and a complementary meniber having a hinge pin connection with tlie outer en'd of said bod-y member and adapted at its outer end portion to fit Within said channelfsaid hood partially inclosing and concealing the hinged end of said complementary member and adapt-ed to form a stop to limit the movement of the complementary member in one direction. 4

In testimony whereof I 'hereunto .aflix my signature. e
